transforming an XML document to a GraphML

[FBS]

Hi everybody,

I want to make a program that transforms an XML document to a GraphML
mark-up that displays the XSLT tree view of the document and obviously I
could use SAX, DOM or XSLT or maybe a combination. It's always interesting
to know which way is the easiest but what I wonder is if anybody could refer
me to some concrete code examples to start with.

Best Regards,
